This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If smaller distribution class units
Liquid transformers under 10MVA threshold use lower capacity subheading.
If bare tank or radiator shipped separately
Transformer enclosure components without windings classify as parts.
If other electrical machines with electrical converters
Hybrid transformer-converter assemblies may fall under broader electrical machinery.
